What is the use of APIs in Programming Languages?

What is an API?

The API is an abbreviation for the Application Programming Interface, which means a set of protocols and routines that the computer system, computer library, or application provides to other applications to perform a services to those applications.

In computer programming, an application programming interface(API) is a set of subroutine definitions, communication protocols, and tools for building software.

When can we use API?

The APIs can be used to communicate with the operating system(WinAPI), with databases(DBMS) or with communication protocols(Jabber / XAMPP). In recent years, multiple social networks are joined such as Twitter, Facebook, Youtube, Flickr, LinkedIn, etc. and other online platforms such as Google Maps, WordPress etc. which has become simple with social media marketing, more traceable and more profitable.

The important thing you need to know about the API is that it allows third parties to use information that they could not access. Thus, unnecessary paperwork is eliminated, since the technology obtains information that is in a closed and verified environment.

API Security

Another important thing about the API is security. In general, APIs only allow a limited scope of action, taking the provisions so that confidential information of the company cannot be manipulated for other purposes.

One of the keys to the functioning of the APIs is the ease of integration. This is a very important thing you need to know about API. These tools have to be simple to integrate with other software so that communications can be developed successfully.
